Each person on a team brings a unique perspective to the process; i.e., how things work; what happens when changes are made, and how to sustain improvements during daily work. Contributions are made from each individual's skill set and the team's synthesis of ideas.
Division of labor is the economic term for the practice of assigning small parts of a complicated job to individual workers who specialize in doing just their small part.
Division of labour, instead, refers to the allocation of tasks to individuals or organizations according to the skills and/or equipment those people or organizations possess. Often division of labour and division of work are both part of the economic activity within an industrial nation or organization.
